Dentists, dental hygienists, and, in many states, dental assistants can place sealants. State practice acts make the determination as to who can diagnose, supervise, and place sealants. Many states require some type of educational program, sometimes with a laboratory as well as a clinical program, to qualify auxiliaries to place sealants.
Placing sealants is not without problems. New materials and improved dental equipment has certainly made the application procedure easier and more successful. Potential problems start with the age of the patient. Many 6- to 7-year olds have never had a dental procedure outside of examinations and cleanings. This procedure should be as pleasant as possible; this might be the introduction of dentistry to a child and if the least bit traumatic could set a pattern for life.
